.SH NAME
std::chrono::year_month_weekday::operatorsys_days, \- std::chrono::year_month_weekday::operatorsys_days,

.SH Synopsis

   constexpr operator std::chrono::sys_days() const noexcept;         \fB(1)\fP \fI(since C++20)\fP
   constexpr explicit operator std::chrono::local_days() const        \fB(2)\fP \fI(since C++20)\fP
   noexcept;

   Converts *this to a std::chrono::time_point representing the same date as this
   year_month_weekday.

   1) If year().ok() && month().ok() && weekday().ok():

     * If index() == 0, returns a sys_days that represents the date 7 days prior to the
       first weekday() of the year and month.
     * Else, returns a sys_days that represents the date (index() - 1) * 7 days after
       the first weekday() of the year and month.
   Otherwise, the returned value is unspecified.
   2) Same as \fB(1)\fP, but returns local_days instead of sys_days. Equivalent to
   local_days(sys_days(*this).time_since_epoch()).

.SH Example


// Run this code

 #include <chrono>
 #include <iostream>
 using namespace std::chrono;

 int main()
 {
     constexpr auto ymwd{Tuesday[2]/11/2021};
     std::cout << ymwd << '\\n';
     // convert from field-based to serial-based to add hours
     constexpr auto sd = sys_days{ymwd} + 24h;
     std::cout << sd << '\\n';
     constexpr auto ymd = floor<days>(sd);
     static_assert(ymd == November/10/2021);
 }
